abstract="Background: The electronic health record sharing system (eHRSS) was implemented as a new health care delivery platform to facilitate two-way communication between the public and private sectors in Hong Kong. Objective: This study aimed to investigate the perceptions of and factors associated with the adoption of eHRSS among patients, the general public, and private physicians. Methods: Telephone interviews were conducted in 2018 by using a simple random sampling strategy from a list of patients who had enrolled in the eHRSS and a territory-wide telephone directory for nonenrolled residents. We completed 2000 surveys (1000 each for enrolled and nonenrolled individuals). Private physicians completed self-administered questionnaires, including 762 valid questionnaires from 454 enrolled physicians and 308 nonenrolled physicians. Results: Most participants (707/1000, 70.70{\%}) were satisfied with the overall performance of the eHRSS. Regarding registration status, most nonenrolled patients (647/1000, 64.70{\%}) reported that ``no recommendation from their physicians and family members'' was the major barrier, whereas more than half of the physicians (536/1000, 53.60{\%}) expressed concerns on ``additional workload due to use of eHRSS.'' A multivariate regression analysis showed that patients were more likely to register when they reported ``other service providers could view the medical records'' (adjusted odds ratio [aOR] 6.09, 95{\%} CI 4.87-7.63; P
